N=5for a geometric progression, the nth term is a(r)^n-1. a is the first term. r is the common ratio.so,A(R)^n-1 = a(r)^n-1A=162, R=54/162 for the 1st geometric progression.a=2/81, r= (2/27)/(2/81) for the 2nd geometric progression.solve and get the value for n.

hope this helped!still, if you are having doubt, ask me where u couldn't understand n i will help :)
